The purpose of this study is to compare the chemical compositions of two plants in the genus Chamerion, and to relate their compositions to how they adapted to such different soils – river beauty preferring wet, mineral rich soil, such as around glacier streams, and fireweed preferring dry, organic rich soils, like areas that recently […]
C20-P: Methods for Tannin Purification, Quantitative and Qualitative Analysis, and Quality Control
Tannins are plentiful in plant based foods. Due to their unique chemistry, they have important effects on the health of humans and other animals. However, the tannin itself is not absorbed; rather, the gut microbiome breaks it down and its decomposition products are absorbed. This makes studying the effects of dietary tannins difficult. To combat […]
B28: Separation and Characterization of Polyphenols in Salix Pulchra for Future Isotopic Studies
The availability of C13 labeled willow tissue (Salix pulchra) has pushed the need for extraction and characterization of polyphenolic compounds within the plant. A method of separation and purification of tannin from the willow plant has been established, but the identity of the extractable non-tannin polyphenols present in willow is not currently known. In order […]
